IMPROVEMENT IN REVOLVING FIRE-ARMS.

Specification forming part of Letters Patent No. 35,657, dated June 17,1862.

To all whom t may concern:

.Be it known that I, JOHN H.V1o1inas, of Worcester,-in the county ofVorcester and State of Massachusetts, have invented a new and usefulImprovement in Revolving Fire- Arms; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming a part of thisspecieation, in which- Figure 1 is a side view of a pistol with myimprovement. Fig. 21s a longitudinal central section of the same. Fig. 3is a top view of the same, partly in section.

Similar letters ot' reference indicate corresponding parts in theseveral figures.

This invention consists in the employment, in a revolving lire-arm, of acontinuous frame rigidly attached to the barrel, inclosing the cylinderlengthwise, and pivoted to the stock in such manner as to enable therear part to fold into the breech-piece and to form a recoilplateindependent of the breech-piece for relieving the breech-piece ot' thestrain of the recoil, such frame allowing the cylinder and breech-pieceto be separated for the introduction of the cartridges into the chambersat the rear thereof.

It further consists in so applying the cylinder axis-pin, in combinationwith such continuous frame, that it passes through the said frame andcylinder from front to rear thereof and enters a hole in thebreech-piece in such manner as to secure or assist in securing the saidframe in proper connection with the breechpiece.

To enable others skilled in the art to apply myinvention to use, I willproceed to describe it with reference to the drawings.

A is the continuous frame for the reception ot' the cylinder, made inthe same piece with the barrel B, or having the latter screwed into orotherwise rigidly attached, the said frame being just long enough forthe reception ol the many-chambered cylinder `F and of the flanges ofthe metallic cartridges, which are left protruding through the rear ofthe cha-inbers thereof.

C is the stock-frame, having the circular breech-piece D, which coversthe rear of the cylinder, made in the same piece with it, and a portionof it extending forward from the bottom of the breech-piece, as shown ate, far enough for the connection with it of the lower front angle ot thecontinuous cylinder-fraaie A by means of a pivot or hinge-joint, a. Theback ot' the frame A, which is a little wider than the caliber ot' thechambers, is tted to a groove, b, provided for its reception in thebreech-piece, and the lower side of the said frame is fitted to a grooveprovided for it in the part c of the stock-frame.

E is the cylinder axis-pin, inserted through a hole in the frontof thecylinder-frame A,

through the center of the cylinder, through a hole in the rear of thecylinder-frame, and into a hole, e, in the center of the circularbreechpiece. This pin, when secu-red in the cylinder-frame by suitablemeans applied near its front end, serves by its entrance into thebreech-piece to secure or assist in securing the cylinder-frame to thebreech-piece, but other meansforsecuring the frame may be employed.

To insert the cartridges in the chambersff of the cylinder, the axis-pinE is drawn. forward far enough to remove its rear end from the hole e inlthe breech-piece D, and the barrel and stock are folded downward fromthe hinge-joint a to expose the rear end of the cylinder, whose chambersare open at the rear for the reception of the cartridges. When thebarrel and stock are thus l'olded down the cylinder is free to be turnedby hand upon the axis-pin. After the chambers have all been loaded thebarrel and stock are moved upward again relatively to each other fromthe joint a, and the back part of the frame is thus caused to enter thegroove` b in the breech-piece, and the pin E is pushed back again intothe hole c in the breech-piece. In firing, the back part of the frame Aconstitutes a recoil-shield independent of the breech-piece D and stock,which are thus relieved of the force of the recoil.

Whatl claim as my invention, and desire to secure by Letters Patent, is

1. The continuous cylinder-frame A, rigidly attached to the barrel andcombined with the breeeh-pieceD, to fold into a. groove provided aforward direction through the cylinder-frame therein, for its reception,substantially as and and cylinder and into a hole in the center of forthe purpose herein specified. the breech-piece, substantially as and forthe 2. 'Hinging the lower front angle of said purpose herein specified.continuous frame A to a portion c 'of the stock-frame which projectsforwer zrom the JOHN H' VIOKBRS' bottom ofthe breech-piece D,substantially as Witnesses herein specified.
